TCIBCULAR SEAM res snwnn ARTICLES.

To all to 710m it at cy concern Be it known that 1, MAX DRUCKERMAN, a

citizen of the Jn'ited States, and a resident of Brooklyn, in the county of Kings andi State of New York, have invented certain new and useful Improvements in Circular-j Seams for Sewed Articles,'of which the fol-j;

lowing is a specification, taken in connectionwith the accompanying drawing, which forms a part of the same. I I

My invention relates to embroidery which is usually done by machine upon any suitable fabric, though it is to be distinctly;

understood that my invention covers em-1 broid'ery upon any material through which;

the needlescarrying the needle threads can pass.

The circular seam or embroidery covered by my present application may be used three different forms of my embroidery rep-,

resenting flowers upon a twig; Fig. 2 is a plan'view of the obverse of one of the flowers in Fig. 1, on an enlarged scale, showing my embroidery formed with two separate and independent needle'threads, and one shuttle or locking thread; Fig. 3 is a plan view of the reverse of the embroidery shown in Fig. 2, many of the stitches being omitted for purposes of illustration; Fig. 1 is a seo tional view of a piece of fabric and a dia-; grammatic view of two needles and two needle threads employed in making the embroidery shown in Fig. 2 and Fig. 3; Fig. 5 is a. vertical sectional view substantially on, tlieline of Fig. 1; Fig. 6 is a plan View of the obverseof the fabric showing a little different form of en'ibroidery in which the needle threads 'do not overlap, the figure being on an enlarged scale; Fig. 7 is a plan View of a further modification in which three needle threads are employed, the diameter of the embroidered seam being substantially the same as that shown in Fig. 6 in which two needles are employed; and Fig. 8

1s a plan View of a further modified form of my embroidery in which three different needles are used, but the diameter of thec'irocular embroidery seam is enlarged.

In the illustrative embodiments of my invention, shown in the drawings, 1 is apiece of material through which the needles 2 and 3, Fig. a, can pass. Usually this material is some woven itabrlc, though, of course, it is to be limited to such material. This material 1 is provided with an opening 4 and 011 the obverse has a plurality of what, for convenience, will be termed independent primary needle threads 5, 5 which are threadedthrough the fabric 1 by the needle 2 operating in a Zig zag manner. These primary needle threads 5, 5 on the reverse form the primary needle loops 6, 6 extendingfronr near the circumference of the circular seam toward its axis, and are locked or caught by theshuttle or looking thread 7. They also form the primary loops 10, 10 on the reverse extendingoutradially from the eenlooking or shuttle thread 7 On the obverse "also is a plurality of secondary needle threads 8, 8, threaded through the fabric '1 by the secondary needle '3 in the ordinary zig zag manner, both needles Qand 3 being preferably mounted on the same head. These secondary needle threads 8, S on the reverse form the secondary inwardly extending needle loops 9, 9 which are also caught or locked by the same shuttle or, looking thread 7 They also form the radially extending secondary needle loops 11, 11 which are also connected by the same locking 0r shuttle thread 7, the one shuttle thread serving to look all the loops formed by the needle '95 threads. I also preferably, though not necessarily, place a binding cord 12 around the edge of the opening 4, which cord is secured in place by the different needle threads?) and 8. It will be noted that in thisfformp shown in Figs. 2, 8, a and at 13 in Fig. 1, the embroidery is formed with independent needle threads which overlap each other. This gives a thick raised effect to the medallion or embroidery on that portion of the circular scam in which the plurality of needle threads are laid down. The relatiye length of the thickened portion of the medallion can, of course, varied as found. convenient or eXpedient. For purposes of' illustration I have in Fig. 5 shown the raised portion formed by the double thickness of needle threads extending from the opening 4 out to the point 14. From that point to the circumference 15 of the embroidery only the secondary needle threads 8 would appear and consequently the portion 16, Fig. 5 of the embroidery would be thinner than the other portion. This gives a very handsome effect to the embroidery as it permits the embroidery seam to taper 0K in thickness from the center to its circumference. It is, of course, to be understood that if the usual number of threads were shown, both the obverse and reverse of my circular seam would have to be illustrated as a substantially solid black ring. In this form of my invention the take up mechanism of the machine serves to tighten the primary needle threads 5 around the edge 17 of the opening 4 whether or not the binding cord 12 is used. In some cases I may form my circular seam as shown in Fig. 6 and at 18 in Fig. 1. In this form the fabric 1 on its obverse is provided with a primary needle thread 19 which extends part way to the circumference of the embroidery and on the reverse forms the primary needle loops 20, 20 which cooperate with the shuttle thread 21, th1s primary needle thread serving to bind the edge 22 of the opening 23, it, of course, being understood that in the completed article the number of threads are greatly increased over those shown in this figure which has to be more or less diagrammatic. A cord 12 may be employed as in Fig. 2 and Fig. 3 if desired, The secondary needle thread 24 is also upon the obverse of the fabric 1 and extends out to the periphery 25 of the complete circular seam forming on the reverse the secondary needle loops 26, 26 which are also caught by the same shuttle or looking thread 21. In this form of my invention the primary and secondary needle threads 19 and 24 do not overlap.

In Fig. 7 and at 27 in Fig. 1, I have shown the fabric 1 having an embroidered circular seam of substantially the same diameter as that shown in Fig. 6 but instead of using two needle threads I employ three needle threads; 28, 28 being the primary needle threads threaded by the primary needle (not shown); 29, 29 being the secondary needle threads threaded by the secondary needle (not shown) and 30, 30 being the third set of needle threads,- all the needle threads being locked or caught by the singleshuttle thread 31. In this form I have shown the different needle threads overlapping. In some cases I may use three needle threads 32, 33, 34, Fig. 8, all cooperating with a single shuttle thread 35. In this instance the threads are the same as those shown in Fig. 7 except that the diameter of the circular seam has been enlarged and the throw of the needles increased from that shown in Fig. 7.

By my invention I am enabled to get the most beautiful shading effects entirely regardless of whether or not the needle threads overlap each other. I imitate embroidery flowers or similar articles, by shading my circular seam from the center out toward the circumference of the embroidery, or I reverse this shading by shading the embroidery from the circumference in toward the center depending upon the particular flower or article being imitated. This is done for example by having a primary needle thread 5 of one color and having a secondary needle thread 8 of a different color. This is also true of the other primary and secondary needle threads 19 and 24, Fig. 6, and also of the triple needle threads 28, 29 and 30, Fig. 7, and 32, 33 and 34, Fig. 8. Where more than two needle threads are employed, the shading can be more delicate, as, of course, with three or more needle threads the shading will be more delicately and perfectly done in that the colors merge from one needle thread into the next and from that into the third and so on. lVhere the needle threads overlap this shading is particularly pleasing. While I have shown only two or three needle threads, it is, of course, to be understood that my invention is not to be limited to this number.

Having thus described this invention in connection with illustrative embodiments thereof to the details of which I do not desire to be limited, what is claimed as new and what it is desired to secure by Letters Patent is set forth in the appended claims.

1. A circular embroidery seam as an article of manufacture consisting of a piece of material having an opening and a plurality of independent radial and horizontal needle threads all extending out radially and lying on the face or obverse of the material, at least one set of independent needle threads extending into and binding the edge of the opening needle thread loops on the back or reverse of the material and a single shuttle or looking thread looking the loops of the different independent radial needle threads.

2. A circular embroidery seam as an article of manufacture consisting of apiece of material having an opening and a plurality of independent radial and horizontal needle threads all extending out radially from the opening and all lying on the face or obverse of the material, said needle threads overlapping each other on the face of the fabric, at least one of the independent needle threads being threaded into the opening in the material and serving to bind its raw edge needle thread loops on the back or reverse of the material, and a single shuttle thread locking the loops of the ditt'erent overlapping independent radial needle threads.

3. A circular embroidery seam as an article of manufacture consisting of a piece of material having an opening, a cord surrounding the opening and a plurality of independent radial and horizontal needle threads which overlap each other on the face of the fabric, at least one of the independent needle threads being threaded into the opening in the material and serving to bind its ravv edge and the cord needle thread loops on the back or reverse of the material, and a single shuttle thread locking the loops of the different overlapping independent radial needle threads.

l. in embroidered medallion as an artiele of manufacture comprising a piece of embroidery having an opening and three radial needle threads of different colors, at least one of the needle threads binding the ravv edge of the opening, and at least one of the other needle threads being laid down on top of said needle thread to give a raised etl'ect to the medallion, the different colors 1 of the needle thread permitting various coloring and shading of the embroidered medallion needle thread loops on the back or reverse of the material, and a single shuttle thread to lock the loops of the different colored needle threads.
